STOVE.

SPECIFICATION forming part of Letters Patent No. 287,453, dated October 30, 1883.

Application filed May 5, 1883. (No model.)

To all whom it may concern Be it known that I, GUY W. MOALLISTER, of Boston, in the county of Suffolk, State of Massachusetts, have invented a certain new and useful Improvement in Stoves, of which the following is a description sufficiently full, clear, and exact to enable any person skilled in the art or science to which said invention appertains to make and use the same, reference being had to the accompanying drawings,

forming a part of this specification, in which-- Figure 1 is an isometrical perspective view of my improved stove, a portion of one of its sides being represented as removed to show the mixer and combustion-chamber. Fig. 2 is a vertical longitudinal section of the mixer and combustion-chamber; Fig. 3, a view of the fuel-reservoir; Fig. 4, a view of the supplytank and air-pump; Fig. 5, aside elevation of the coil; and Fig. 6, a vertical transverse section, showing the burner.

Like letters of reference indicate corresponding parts in the different figures of the drawings.

My invention relates to that class of stoves which are designed to use liquid fuel or burn the hydrocarbon oils; and it consists in a novel construction and arrangement of the parts, as hereinafter more fully set forth and claimed, by which a simpler, cheaper, and more effectiye device of this character is produced than has heretofore been employed.

The nature and operation of the improvement will be readily understood by all conversant with such matters from the following explanation, its extreme simplicity rendering an elaborate description unnecessary.

In the drawings, A represents the body of the stove, B the mixer, and C the combustionchamber. The mixer is preferably cylindrical in form, having slightly-fiaring sides, and is provided with a perforated top, D, and foraminous bottom E, being supported in the body of the stove on the platform m, so as to leave an air-space, F, beneath the same on all sides. The combustionchamber, which is also preferably cylindrical in form and has an open top, is centrally disposed within the mixer, extending downwardly through the bottom of the same, as best seen in Fig. 2, and being provided with an air-register, G, in its bottom. A supply or induction pipe, J, passes Disposed in the upper part of the pipe K,

and coincident with the vertical axial line of the chamber 0, there is a burner, a. This burner consists of a plug of platinum or other substance not readily fused or injured by intense heat, and is provided with a fine orifice, t, at its inner end, and the flaring or tunnelshaped mouth, 2, as best seen in Fig. 6.

Arranged centrally beneath the helix H, above the register G, there is a small openmouthed tank, f, provided with the horizon- 7 tally-arranged pipe M, which extends outwardly' through the walls of the stove, being provided at its outer end with the stop-cock h and cup I.

Avacuum or relief chamber, N, is attached to the pipe J, outside of the stove proper, and beneath this there is a stop-cock, 1', connected by the short pipe 12 with a nozzle 'or dischargeorifice, w, on the pipe'K.

A reservoir, 0, for containing the oil for 8 5 furnishing the stove, is disposed on the shelf Q, which should be located considerably above the plane of the chamber 0, and is connected with the pipe J by means of the supply-pipe R, provided with the stopcock q. A rod, j, 0 is journaled vertically on the outer side of the reservoir, and provided at its upper end with a gear, p, which intermeshes with the gear t, disposed on the rod b, the rod being connected with the stopcock g on the end of the pipe R, 5' within the reservoir, and adapted to open and close the same whenthe rod j is turned to the right or left, as the case may be. The oil for supplying the reservoir is contained in the barrel or tank U, preferably disposed in a mo cellar below the floor on 'which the stove stands, the tank being connected with the reservoir by meansof the pipe W, provided with the stop-cock y. An air-pump, 14, is provided for forcing the oil from the barrel into the reservoir; but as the pump is of ordinary construction, and no claim is made therefor, a more particular description of the same is deemed unnecessary.

In the use of my improvement the stop-cock q is closed, the stop-cock 3 opened, andthe reservoir 0 filled by pumping from the tank U, after whiehthe cock y is closed. The stopcocks (l a h r are then closed and the cup Z filled with oil, after which the stop-cock h is opened, permitting the oil in the cup to flow into the tank f, and then again closed. A door (not shown) connecting with the air chamber or space F is then opened and the oil in the tank 0 lighted, after which the door is closed and the register G opened by means of the rod 23. The stop-cock q is next opened and oil let into the stove through the pipe J, passing upwardly through the coil or helix H, which having been previously heated by the flames from the burning oil in the tank f, evaporates or converts the oil into gas, which passes downwardly through the pipes L K and out of the burner n, where it is ignited, the flames of the burning gas passing upwardly through and around the coils of the helix'and out of the open mouth or top of the combustion-chamber G into the mixer B, where it is mixed with the air, which enters through the bottom E, and the combustion is perfected, the heated air and products of combustion passing out of the mixer through the perforated cover D, where they may be utilized for heating and cooking purposes, in a manner which will be readily obvious without a more explicit description.

The burner consists of a plug adapted to fit an opening in the pipe, and having an inwardly-tapered perforation and an upper face flush with the outer surface of the pipe, where the oil in the latter will be more readily heated and prepared for burning.

It will be obvious that the fire may be readily extinguished in the stove by closing the stop-cock q, thereby shutting on the supply of fuel. When the stopcock qhas been closed and the oil between said cock and the burner n consumed,the stop-cocks a h maybe opened, and the oil, if any, in the pipe K, between the burner n and its outer end,drawi1 into the cup Z, from whence it will pass into the tank f, to be used for kindling the fire, as hereinbefore described.

The object of the stop-cock r and pipe 1) is to enable oil to be drawn directly from the pipe J and passed through the nozzle w into the cup I and tank f, for kindling purposes.

A deflector, 25, isarranged over the mouth of the combustion-chamber O, to deflect the burning gases and cause them to be brought more thoroughly into contact with the air in the mixer B.

The air in the chamber or space F, being heated by the oven and surrounding walls of the stove before passing into the mixer through the bottom E, thereby assists in maintaining a high temperature in the mixer and greatly promotesthe combustion of the gases.

Having thus explained my invention, what I claim is 1. The improved stove herein described, the same consisting of the body A, provided with the mixer B, having the perforated top D and foraminous bottom E, the combustionchamber 0, having an open top and provided with the register G, the helix H, provided with the pipe J, and the pipe K, provided with the burner n, in combination with means for supplying the stove with oil, substantially as set forth.

2. In a stove substantially such as de- I scribed, a coil or helix in which the oil is evaporated or converted into gas, a combustion-chamber in which the coil is disposed, a

mixingchamber surrounding said combustion-chamber and extending above the same, into which the burning gases are carried and mixed with air to perfect combustion, aburner through which the gases pass from the coil in the combustion-chamber, and means for supplying the combustion-chamber and mixer with air and the coil with oil, substantially as described.

3. The combination of a combustion-chain ber, 0, having a burner, a, an oil-tank, f, within said chamber, below said burner, provided with an induction oil-pipe,'m, and a cup, Z, at its outer end.

4. The combination of a combustion-chamber, oil-supply pipe J burner-pipe K, and a supply-pipe, m, for the kindling device, the latter being provided with a cup, Z, and a pipe, 4;, adapted to receive oil from said pipes J K and discharge the same into said cup, substantially as described.

5. The combination, with a combustionohamber, of an oil-supply pipe, J, a burnerpipe, K, connected therewith, and a vertical 'plpe, 1), connecting said pipes J K, and provided with a stop-cock, r, and a nozzle, w, said pipe K being provided with stop-cocks a d, substantially as described.

6. The combination of a combustionchamber, C mixing-chamber B, surrounding the upper part thereof, provided with foraminous disks D E, and a chamber, F, below said mixer, into which the lower part of said combustion -chamber extends, said combustionchamber being provided at said extension with an oil-tank, f, and a register opening into the chamber F, substantially as described.

7 In a stove substantially such as described, the reservoir 9, provided with the rod j, gears 19 t, and rod b, for opening and closing the stopcock g, substantially as shown and described.
